<h2 id="大白"><a href="#大白" class="headerlink" title="大白"></a>大白</h2><p>难度几乎没有，题目告诉我们是不是屏幕太小，点击属性看一下，长宽差距挺大的，尝试把长宽改一下，发现flag<br><img src="https://ftp.bmp.ovh/imgs/2021/03/b65c42fac209e72f.png" loading="lazy"></p>
<h2 id="爱因斯坦"><a href="#爱因斯坦" class="headerlink" title="爱因斯坦"></a>爱因斯坦</h2><p>最初看到文件中写的是misc2.jpg，本以为是有两个图用两个图做色差得到答案，结果完全想多了，试图用foremost分离找出另一张图，结果找到了一个压缩包，里面是flag，但是flag是加密的，绕了半天没找到方法后又回来看misc2.jpg，结果在属性里找到一个备注，试一下果然是压缩包的密码，从压缩包里得到flag<br><img src="https://ftp.bmp.ovh/imgs/2021/03/230d94540aab0967.png" loading="lazy"></p>
<h2 id="N钟方法解决"><a href="#N钟方法解决" class="headerlink" title="N钟方法解决"></a>N钟方法解决</h2><p>打开后得到一个key.exe 执行不了，看看是不是权限的问题，于是用管理员权限开，没有结果，再试试压缩包里有没有其他隐藏文件，也没有找到，想用010 editor打开看看有没有线索，然后没找到这个文件，接着发现可以用subline text打开，并且打开后说的很明确了，与base64和jpg有关系，但是我不知道base64可以转化为图片的，于是又用关键词搜索一下，找到可以转化，转化完是个二维码，扫一下得到flag<br><img src="https://ftp.bmp.ovh/imgs/2021/03/023a65023a9b74cc.png" loading="lazy"></p>
<h2 id="wireshark"><a href="#wireshark" class="headerlink" title="wireshark"></a>wireshark</h2><p>这题都对不住自己的分值，打开wireshark，搜索关键词，追踪tcp流，找到flag，提交<br><img src="https://ftp.bmp.ovh/imgs/2021/03/84e59ef1d4ade9eb.png" loading="lazy"></p>
<h2 id="infogate"><a href="#infogate" class="headerlink" title="infogate"></a>infogate</h2><p>  进去就让输入账号密码（最开始我以为他的guest/guest是让我用guest登录，但是没有密码，后来我才知道/是给我分开，账号密码都是guest），于是我试了一下全能密码，第一次可能代码不太对，进去了网页但是是guest账户进去的，再试了一次是以admin账户进去的，进去以后两个比较一下，多了一个upload，<br><img src="https://ftp.bmp.ovh/imgs/2021/03/c131cc4421ffb6ad.png" loading="lazy"><br>需要上传一个txt文件，返回一个地址，但是地址不能访问，错误403，查了一下，没有权限，就感觉很奇怪，明明是admin账户，却没有权限访问，然后试了各种各样的方法，都没有办法解决，最终没有做出来</p>
<h2 id="重定向的海洋，"><a href="#重定向的海洋，" class="headerlink" title="重定向的海洋，"></a>重定向的海洋，</h2><p>最开始没看到左上角有个关于是提示，一脸雾水，看到后从第三关开始解，提示是一个加密方式，点开源代码发现一个js文件，但是文件乱码了，换了一个浏览器，又出了新的乱码，懵了，这个还能随便变化的？<br><img src="https://ftp.bmp.ovh/imgs/2021/03/dddc8647f3efe02e.png" loading="lazy"><br><img src="https://ftp.bmp.ovh/imgs/2021/03/d804650564a1a249.png" loading="lazy"><br>问了一下要以谷歌为准，但是谷歌也是乱码，很迷，尝试一下乱码恢复，并没有什么用，无意中看到编码方式是utf-8，或许题目的编码方式不是，改一下编码方式，解决问题，得到part3，回过头来，第一关，密码在源代码里 ，得到part1，再去第二关，提示是头，看了一下head标签，没有找到问题，接着想到一个叫做响应头的东西，用bp看了一下，没找到响应头（不知道bp那个头是什么），再从谷歌中找响应头，找到了part2，组合一下得到答案</p>
<h2 id="神秘龙卷风"><a href="#神秘龙卷风" class="headerlink" title="神秘龙卷风"></a>神秘龙卷风</h2><p>这题做的靠后的主要原因是，没找打rar解密，找到解密软件后直接破解，得到一个一+.&gt;组合的密码，印象中好像看到过这个密码，从本地准备的奇葩密码中找到这种密码，解密得到flag<br><img src="https://ftp.bmp.ovh/imgs/2021/03/a46baa8486dd7b75.png" loading="lazy"></p>
<h2 id="刷新过的图片"><a href="#刷新过的图片" class="headerlink" title="刷新过的图片"></a>刷新过的图片</h2><p>这道题就是完全没什么思路，还找到莫名的appdouble文件，也没解决，首先确定这道题肯定是隐写，提示是刷新，联想到f5，但是并没接触过这是什么，从我的ctf tools中找了一下，有一个意外惊喜，有一个图片隐写的文件名叫做f5，打开后果然没错，就是这道题的解码方式，运用解码，得到一个txt，打开后是乱码，但是解码肯定是没有错的，用kali的file功能看一下，这实际上是一个zip文件，<br><img src="https://ftp.bmp.ovh/imgs/2021/03/fbef91c08974293d.png" loading="lazy"><br>然后打开后还是个加密文件，之前下好了解密软件，但是解密软件却反馈这个没有密码，很奇怪，后来得知这是一个伪密码，在十六进制中修改一下就可以跳过了，得到flag</p>
<h2 id="其他"><a href="#其他" class="headerlink" title="其他"></a>其他</h2><p>其他题目大概看了一下，基本全是盲点，完全不会的节奏，能做的都已经写了，尽力了</p>
